一个超级强大的图片加水印的类(8)

        if ($this -> waterType == 0) { 

            $this->waterstr(); 

        } else { 

            $this->waterimginfo(); 

            $this->waterimg(); 

        } 

        switch ($this -> srcImg_info[2]) { 

            case 3 : 

                imagepng($this -> im, $this -> srcImg); 

                break 1; 

            case 2 : 

                imagejpeg($this -> im, $this -> srcImg); 

                break 1; 

            case 1 : 

                imagegif($this -> im, $this -> srcImg); 

                break 1; 

            default : 

                die('添加水印失败！'); 

                break; 

        } 

        //图片合成后的后续销毁处理 

        imagedestroy($this -> im); 

        imagedestroy($this -> water_im); 

    } 

} 

使用方法示例：

//实例化对象  

$obj = new WaterMask('img/10451.jpg');        

//类型：0为文字水印、1为图片水印

$obj->waterType = 0;                      

//水印透明度，值 越小透明度越高

$obj->transparent = 15;                   

//水印文字 

//$obj->waterStr = '生日快乐';
